DAVID HINDAHL, OF CHICAGO, ILLINOIS, ASSIGNORS TO CHICAGO, ILLINOIS, A CORPORATION OF RAILWAY DUMP CAR.

Application filed November The present invention relates to railway dump cars.

The present invention has been illustrated and will be described in connection with a railway dump car of the convertible type.v

that is, a type so constructed and arranged that said car may be used as a flat bottom car or as a dump car. According to the structure illustrated, dumping mechanism is provided by means of which lading may be deposited outside of the tracks upon which the car is mounted and which the car is mounted. Operating mechanism is provided for controlling the dumping mechanism for thetwo classes of dumping referred to.

It is an object of the present invention to provide a construction of car and dumping mechanism which will be convenient for use and sturdy in construction and which will not interfere with other parts of the car.

A further object of the present invention is to provide a construction of dumping mechanism which is readily applicable to well known designs of dump car, and which will avoid certain interference with other parts of the car, which interference is now at'times encountered in service.

The mechanism for dumping lading between the tracks upon which the car is mounted involves, as a rule, a longitudinally extending rotatable shaft. As cars are at present commonly constructed, said longitudinally extending shaft has been located in a position such that'when the car is round ing a sharp curve there is an interference between said shaft and the trucks of the car. It is an objectof the presentinvention to provide a construction in which this interference is eliminated.

Further objects will app-ear as the description proceeds.

Referring to the drawings- Figure 1 is a transverse sectional view of a convertible car embodying the principles of the present invention;

Figure 2 is an end elevation of the car shown in Figure 1; and Figure 3 represents a tion.

The car chosen for illustration comprises the side walls 1, 1, and the end walls 2, 2. Stakes 3, 3 may be provided .for strengthening the side Walls 1, 1.

detail of construcbetween tracks upon 1,1923. Serial No. 672,058. v

Arranged medially of the car in a longitudinal direction are the hopper forming walls 4' and 5, of which the wall 5 is provided with a swinging door 6 pivoted for swinging movement about the axis 7. chain 8 is provided for controlling the swinging door 6, said chain 8 being mounted upon the longitudinally extending rotat-- able shaft 9. The mounting of said shaft will be referred to in detail hereinafter.

Mounted for swinging movement along axes placed near to the upper extremities'of walls 4' and 5 are the swinging doors 10 and 11, which doors swing about the axes 12, 12. Said doors 10 and 11 are adapted selectively to assume inclined positions, as indicated by the door 10 in Figure 1, or horizontal positions as indicated by the door 11 in Figure 1. When said doors 10 and 11 are in their inclined positions, their swinging edges will abut against and be supported by the side walls 1, 1 of the car and in these inclined positions said'swinging doors 10 and 11 will form continuations of the hopper walls 4 and 5. Said swinging doors 10 and 11, when swung to their horizontal positions, form part of the flat bottom of the car.

Pivoted near the axes 12, 12 are other swinging doors 13 and 14, which swing about the axes 15, 15. v The doors 13 and 14 are adapted to assume-horizontal positions whereby they will complete the bottom wall of the car when the swinging doors 10 and 11 are in their horizontal positions. The swinging doors 13 and 14 are also adapted to assume inclined positions as indicated by the door14 in Figure 1, whereby lading from the car may be directed outside of the tracks upon which the car is mounted. The doors 13 and 14 are controlled by the chains 16 and 17, respectively, which in turn are controlled by the longitudinally extending rotatable shafts 18 and 19, respectively.

The numeral 20 indicates a cross-tie which underlies the doors 10 and 11 when said doors 10 and 11 are in their horizontal positions. It has been common practicev in convertible car construction to mount the operating shaft 9 below the cross-tie 20, which arrangement has brought said operating shaft '9 to a level dangerously close to the trucks of the car, which trucks are indicated by the wheels 21, 21 of'said trucks. As a result of this arrangement interference-has fill ' said operating shaft: 9.

been encountered between the longitudinally extending operating; shaft 9 and the trucks when the car is rounding a relatively sharp curve. According to the present invention the operating shaft 9 is disposed. in a position such that it extends through a hole in the crsstie 20. This arrangement has the advantage that the operating shaftis located at a higher level than heretofore. Inasmuch as the operating shaft 9 preferably lies outside of the hopper wall 1;, the raising of the level of said operating shaft 9 also involves the result that the operating shaft is moved further from the longitudinally vertical central plane of the car. This last mentioned feature'has the advantage that the operating shaft 9 presents a greater clearance than has heretofore been the case with respect to the hrakestail Q51 and the car coupling mechanism 23 which are located at the ends of the car. The disposition of the operating shaft through a hole in the cross-tie has the further advantage that it affords an opportunity for an improved bearing means for Referring to Figure 3, it will he noted that a bearing member 241 is supportedby the cross-tie 9.0 by means of rivets 25, 25 or other preferred holding means. Inasmuch as the cross-tie 2O ordinarily takes the form of a channel and inasmuch as the hole for the longitudinally extending operating shaft 9 occurs in the web portion of said channel, no practical weakening effect is had upon the cross-tie. The advantage accrues that a simple, inexpensive and effective bearing provided by said crosst-ie for the longitudinally extending operating shaft 9.

According to the structure illustrated, the hopper wall 4- comprises the she-ct steel portion 26 having the offset poi ion 2?, which olfsetportion forms a shoulder for receiving the. portion 28. of the hopper wall t. The sheetsteel portion 26 may be reinforced by the angle 29 and the longitudinally extending operating shaft 9 may be additionally supported by means of the strap 30 which is secured at one end to the sheet steel member 26 and at its other end to loi'igitudinal sills 31, 3.1 forming; part of the frame of the car. It will be noted that the longiutdinal sills 31, 3.1 extend to the top of the cross tie 20, that is, the upper boundaries of said sills are in substantially the same plane as the upper boundary of said cross tie, and that the hopper wall t extends substantially to the upper boundary of its adjacent sill 31. By reason of the sheet steel construction and the angle 2.9 for stiffening same, a struc ture is provided which leaves plenty of room between the hopper wall 4- and the adjacent longitudinal sill 31 for mounting the operati-ng shaft 9 in a position such that said shaft 9 extends through the web of the channel constituting the cross-tie said shaft 9 lies i a Wheels.

The functions of the apparatus above described will be clear without detailed description. Said functions may. be briefly stated, however, as follows:

By reason of the change in the position of the operating shaft 9 from its former position below the cross-tic 20 to a position such that said shaft extends through said crosst-ie, the result is attained that said operating shaft 9 is disposed in a position clear of the trucks so that there is no danger of interference with said trucks even when the car is rounding a sharp curve. Such an arrangement also provides an opportunity for a simple, inexpensive and eifectire bearing for the operating shaft 9, and also has the advantage that good clearance is provided at the ends of the car from the bralrestati and car coupling n'iechanism.

Although a preferred embodiment of the present invention has been described in detail, many modifications may be made without departing from the spirit of the invention. In this patent it is intended to cover all such modifications that fall within the scope of the appended claims.
